What is an iris system?
Just so, how do iris scans work?
Iris scanning measures the unique patterns in irises, the colored circles in people's eyes. Biometric iris recognition scanners work by illuminating the iris with invisible infrared light to pick up unique patterns that are not visible to the naked eye. The final result is a set of pixels containing only the iris.
Also to know is, what is iris recognition used for?
Iris recognition is an automated method of biometric identification that uses mathematical pattern-recognition techniques on video images of one or both of the irises of an individual's eyes, whose complex patterns are unique, stable, and can be seen from some distance.
Iris scanning is literally the best method for biometric identification. The technology is even more accurate than using fingerprint identification, which can sometimes be hard to identify after many years of certain kinds of manual labor that may affect the hands.
